Pulmonary hypertension syndrome (PHS) is a disease that is difficult to overcome for fast-growing broilers. It causes pulmonary vascular remodeling and ascites in broilers. As a classical inhibitor of cancer metastasis, phosphatidylethanolamine binding protein 1 (PEBP1) regulates angiogenesis in the process of tumor metastasis through multiple signal pathways. However, whether PEBP1 can regulate pulmonary artery remodeling in broilers with PHS has not been reported. This study constructed the prokaryotic expression vector of [PEBP1]-pET32a by genetic engineering technology, the recombinant PEBP1 protein was expressed in large quantities, and the PEBP1 polyclonal antibody was prepared by immunizing rabbits with the recombinant PEBP1 protein. Western blot and immunofluorescence results showed that PEBP1 was expressed in many kinds of animal tissues. However, due to the species specificity of polyclonal antibodies, the expression level of PEBP1 protein in broilers and ducks with high homology was significantly higher than that in other species of animals. More interestingly, we found that the expression of PEBP1 protein decreased significantly in broilers with PHS. These studies laid a foundation for further exploration of the mechanism of pulmonary artery remodeling. In addition, the PEBP1 polyclonal antibody provided convenience for further study of the role of PEBP1 in PHS. |
